Abstract:

A bone screw comprising a threaded shank including a distal end portion and a proximal end portion, and defining a first threaded section extending from the distal end portion toward the proximal end portion and adapted for anchoring in cancellous bone, and a second threaded section extending contiguously from the first threaded section toward the proximal end portion and adapted for engagement in cortical bone, with the second threaded section having a finer thread pattern relative to the first threaded section. In one embodiment, the first threaded section includes a first helical threading defining a single lead thread pattern for anchoring in cancellous bone, and the second threaded section includes a second helical threading interleaved with the first threading to define a duel lead thread pattern for engagement in cortical bone. In a further embodiment, the bone screw includes a head portion extending from the threaded shank and configured for coupling to a spinal implant.

US Classification:

606250, 606278

Abstract:

An orthopedic implant is disclosed having at least one passage for an elongated member that is compressible. In certain embodiments, multiple compressible elongated member passages may be provided, or an elongated member passage may be U-shaped and closable by a closure member. Split ring members may be provided in compressible passages and around elongated members. A bone anchor may be connected to the implant so that locking the anchor to the implant compresses one or more of the elongated member passages.
